Title: A hydraulically driven springless fuel injector
Inventor: STURMAN ODED E
IPC: F02M59/10
Filed: 1999-05-03
Abstract: A fuel injector which has a check valve (72) that is hydraulically controlled by a control fluid. A volume of fuel is pressurized within a fuel chamber (88) of the injector by an intensifier (86). The check valve (72) controls the flow of fuel from the fuel chamber through at least one nozzle opening (54) of a valve body. The flow of control fluid is controlled by a control valve (108) which can move between a first position and a second position. When the control valve is at its first position, the control fluid creates an hydraulic force which moves the check valve (72) to a closed position. When the control valve (108) is at its second position, the control fluid moves the check valve (72) to an open position to allow the pressurized fuel to be ejected or sprayed from the nozzle opening(s). The intensifier (86) can also be hydraulically controlled by a control valve (114).

IPC: A61N5/06
Filed: 2000-01-28
Abstract: A method is disclosed for treating blood vessels using endovascular techniques to deliver laser energy. Percutaneous access into the vein lumen will be obtained using an angiocatheter through which a fiber optic line will be introduced. The vein will be emptied of blood using elevation of the limb, patient positioning, compression, or other means. Laser energy will be delivered into the vein lumen using wavelengths from about 532 nanometers to about 1064 nanometers.
